PAPER-MAKiNG MACHINE.

Application filed ApIil 12, 1926. Serial N0. 101,375.

My present invention relates to improvements in paper machines 'of the Fourdrinier type, and particularly to the means in eoaction with the Wire for forming the deckle edge of the paper.

, The invention contemplates an attachment for paper making machines which is simple in construction and operation; which may be installed on the machine with facility and a minimum expenditure of labor, and which may be adjusted with accuracy and convenience to co-act with the wire in the formation of the deckle edges of the paper-web. The invention consists in certain novel combinations and arrangements of parts in connection with stationary edge guides or rulers located at the sides of the web whereby the movement of the web may be controlled and the deckle edges properly fashioned, as will hereinafter be more fully set forth andclaimed.

The present invention is in some respects analogous to that disclosed. in the copending application of Sydney 0. Wentz, Serial No. 72,561, filed December 1, 1925, for paper making machine, which has developed into Patent 1,603,226 dated October 12, 1926.

In the accompanying drawings 1 have il lustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged in accordance with one mode I have devised for the practical application of the principles of my invention.

Figure 1 is a view at one side of a paper maehine showing an end of one of the deckling devices, it being understood that an oppositely arranged decking device is used at the opposite side of the machine, for forming the deckling edges.

Figure 2 is a transverse vertical sectional View at line 2-2 of Figure 1.

Figure 3 is a view in elevation at the outer side of one of the duplicate deckling devices, showing it supported on a side rail or part of the stationary frame of the machine.

Figure 4 is an enlarged detail vertical sectional view at line 44 of Figure 3.

Figure 5 is an enlarged detail view.

Figure 6 is a detail view showing one of the edge-guide or ruler supports.

The device of my invention may readily be attached to machines now in use and substituted for the usual endless deckle belts or guides located at the sides of the machine side rails 1 at the upper longitudinal edges of the machine frame in proximity to the wire screen or endless apron 2, which travels over the brass table rollers 3 as usual. These rolls or rollers extend transversely of the machine and support the working flight of the endless apron or wire which travels longitudinally of the machine. The web is indicated at 4 in Figure 1 as being fashioned on the screen or wire apron, and at each side of the web a deckling device is located similar to that shown in Figures 1 and 3.

The deckle frame which supports the assembled parts of my invention directly over the lateral edges of the wire, includes a pair; of longitudinally extending side plates 5 (only one of which is shown herein) and this plate is supported from its complementary side rail 1 of the machine by means of a pair of horizontal bars 6 and? which extend transversely of the machine and pass through openings near the respective ends of the side plates 5.

The supporting bars 6 and 7 as shown are preferably; of tubular construction to insure lightness'o'f Weight with strength, and each bar is rigidly supported in a block, as 8 and 9, spaced apart and each provided with a split portion 10 and clamping bolt 11 by means of which the respective bars are clamped in their blocks.

Thus when the bolts 11 are loosened the bars may be adjusted transversely of the machine in their clamp blocks to desired position, and then the blocks and bars are rigidly clamped together by means of the bolts. Each block has a base plate or flange 12 with bolt slots 13-tl1erein, and preferably four bolts 14 are passed up through bolt holes in the side rail and the bolt slots of the flange, and nuts 15 are used to clamp the flange to the rail.

Asbest seen in Figure 1 each clamp block is fashioned with a fulcrum edge or rib 16, which may be formed by beveling the underside of the base plate or flange 12 in opposite directions, and this edge, which extends longitudinally of the machine, forms the sole contact between the deckle frame and the side rail of the machine. Thus it will be 'on the paper.

apparent that by manipulating the four nuts of the bolts 14 the blocks may be tilted on their fulcrum edges to desired position for swinging the bars and side plate to adjust the deckling device with relation to the wire.

lh1s swingmg movement, which 1s slight, pei

niits facility and insures accuracy in the adj ustment of the deckle frame, and when the nuts 15 are tightened the frame is held in riglid relation to the machine frame or side rai 1.

The side plates 5 of the deckle frame are adjustable laterally of the machine or wire, on the bars 6 and 7 and for this purpose, at their ends, the side plates are provided with attaching plates as 17 and 18, bolted at 19 to the Outer face of the side plate. Each attaching plate is formed with a collar20 and a set screw or bolt 21 is threaded in a bushing 22 of the collar to frictionally engage the periphery of the bar and thus retain the side plate on the bar in adjusted, rigid rela tion thereto. By this means the side plate may accurately be adjusted laterally of the machine over the edge of the wire or apron, and the adjusted parts made rigid in their relation by means of the screws or bolts 21 in the bosses 22.

At its lower edgethe side plate 5 is fashioned with a retaining, flange 23 for the rubber edge-guide or ruler 24 and these elements, which are disposed at approximately an angle of 45 degrees to the side plate, lie in position with the bent lower edge of the rubber ruler upon the top face of the wire or apron, for the purpose of forming the deckle edge The rubber edge ruler is pressed against and held to the outer face of the retaining flange by means of a retaining bar 25 which extends longitudinally of the retaining flange the full length of the ruler, and frictionally engages the outer face of the ruler. As the lower working edge of the rubber ruler wears away due to frictional contact therewith of' the wire,'the ruler may gradually be adjusted and lowered to compensate for the wear.

The retaining plate is fashionedwith a longitudinally extending tongue or rib 26,- and a series of resiliently pressed levers 27, each pivoted as at 28 in a bracket 29 screwed to the outeir'face of the retaining flange, is provided to retain the ruler against the face of the retaining flange." At their lower ends the levers are fashioned with grooved heads 30 which fit over the rib of the retaining plate to support the plate and press it against the ruler. The levers, which are located at the outer side of the deckle frame, but within the side rails of the paper machine, extend vertically upwardly above the side plate. They are spaced apart at suitable intervals and their number may be varied if desired. At theirupper ends the levers are provided with vertical slots 31 to receive or surround the free ends of a set of fixed screws 32 which project outwardlyfrom the deckle frame and are secured by lock nuts as 33 to posts 34 of the side plate. Between the slotted arm of the lever and the side plate a traveling nut 35 and a spring 36 are located. The spring is coiled about the screw or threaded bar and interposed between the nut and the slotted lever arm, and it will be apparent that by turning the nut'the tension of the spring may be varied. The spring exerts its tension against the lever arm to press the retaining plate against the ruler and retaining flange of the side plate to rigidly hold the flexible, resilient ruler in position.

Various changes maybe made in the combinations and. arrangement of parts as herein shown, within the scope of my claims, without departing from the spirit of my invention, as it will be understood that the exemplified structure is capable of alterations and adaptations to convert it for use under varying conditions in existing machines.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination with a deckle frame including a side plate and a ruler supported therefrom, of transversely disposed supports for said plate, a frame, tiltable blocks for said supports fulcrumed on said frame, and means positioned on opposite sides of the fulcrum -for fastening each of said blocks in adjusted position.

2. The combination in a deckle frame with a side plate having a retaining flange and a ruler, of a retainingplate for the ruler, re-

taining levers pivoted onthe retaining flange and'engagmg the retaining plate, and res1l ient means supported on the side plate and bearing against said levers for pressing the lovers against the retaining plate.
